THREAD-CONTROLLER.

Specification of Letters Patent.

Patented Sept. 24, 1907.

Application filed September 6,1906. Serial N0. 3733.462.

' as there are spindles or bobbins, each of the said plates being provided with a removably attached dome having an elongated aperture at its top for the passage of the thread the edges of which aperture are bent inwards; the dome is also provided with a radial slot leading to a slot in the plate, for allowing the introduction of the thread into the aperture in the dome, each of the said plates being provided directly on its underside with a thread guide, a guiding piece for this latter allowing the thread guide to be shifted during the operation of the machine and a screw device for` securing the thread guide in its adjusted position. In order that this device may also serve for breaking the strange threads run in, the elongated apertures of the hereinbefore described domes may be'provided with slots having sharp edges or, in order that the said device may serve as a thread clearer or threadcleaner, the edges of the elongated apertures of the domes may only be slightly bent inwards.

In the'accompanying drawing: Figures 1 and 2 are a section and a'plan showing the device mounted upon a wool spinning machine of the continuous type while Figs. 3 and 4 illustrate a modification designed to be mounted upon a cotton spinning machine of the continuous type.

Referring first to Figs. l and 2 it will be seen that the device comprises as many metal platesc having domes g as there are bobbins, spindles or threads, the said plates being independent of one another and mounted upon hinges at s so as to be separately lifted when necessary for the removal of the bobbins. These plates c extend each to another solas to constitute in some respects a substantially continuous divided plate with the obj ect of retaining the continuously delivered parts of broken threads and of preventing them from falling down between adjacent plates onto the bobbins. These continuously delivered thread parts which are thus retained are prevented' on the other hand from uniting with a neighboring thread owing to the higher elevation of the domes g and to their smooth side walls upon which the threads cannot climb. Each dome g is removably attached by means of flanges o to the corresponding plate c and has at the top an elongated aperture for the passage of the thread. This aperture comprises four end slots with sharp edges and the edges of this aperture are bent inwards along a curve sufficiently pronounced to enable the woolen thread passing through the said aperture to be properly treated in rubbing against the said edges. The smooth, relatively steep side walls of the domes g allow the down to slide down onto the plates, where it is collected and prevented from fallingl upon the bobbins.

To allow the introduction of the thread into the aperture of the domes g each of the latter is provided with a radial slot y leading to a corresponding slot in the plate c. On the lower side each plate c is provided with a spiral thread guide t in the form of an eye the stem or tail of which is directly secured to the underside of the plate by a guiding stirrup w and a clamping screw zc, this thread guide being thus adjustable in such a way that it can be shifted during the operation of the machine (without being turned) and clamped in any adjusted position.

When-a thread breaks the part of the thread which continues to be fed is stopped by the corresponding plate c on which it accumulates without being able to slide or rise over the dome of an adjacent plate-and become united with an adjacent thread, so that the entanglement or running in of a strange broken thread with an adjacent thread is rendered impossible and the dome-plates therefore constitute an anti-thread entangler.

If an entanglement were exceptionally occasioned by the hand of the workman when attaching a thread, at least one of the threads thus united would be forced to enter one or the other of the end slots of the aperture g of the corresponding dome and become wedged therein and broken, the dome-plates thus performing the function also of a union-breaker.

For continuous cotton-spinning machines the elongated aperture of the domes g is quite plain without the unionbreaking slots, as illustrated in the modification, Figs. 3 and 4. In fact in the latter case the cotton thread is always subjected to. a twist and from this fact possesses a certain resistance so that less breakages take place and consequently also fewer entanglen'ients. On the other hand, this cotton thread can be cleared or cleaned in the dome itself and to this end the front and rear edges of the aperture of the dome g are here only slightly turned inwards, that is to say, along an acute-angled conical surface at the top as shown in The plates c may be rectangular or partly rounded at the front (see Figs. 2 and 4 respectively).

What I claim is:

1. An arrangement for preventing the entanglement or drawing in of strange threads in spinning and twisting machines of the continuous type, formed of independently articulated metal plates extending each to another so as to constitute a substantially continuous divided plate, and each of which is provided with a removably attached dome having at its top an elongated aperture with its edges bent inwardly and provided with a radial slot leading to a slot in the plate for allowing the introduction of the thread into the said aperture in the dome, each of the said plates being provided directly on its under side with a thread guide, a guiding piece for this latter allowing the thread guide to be shifted during the operation of the machine, and a screw device to secure the thread guide in its adjusted position substantially as described.

2. An arrangement for preventing the entanglement or drawing in of strange threads in spinning and twisting machines of the continuous type, formed of independently articulated metal plates extending cach to another so as to constitute a substantially continuous divided plate, and each of which is provided with a removably attached dome having at-its top an elongated aperture with its edges bent inwardly and provided with a radial slot leading to a slot in the plate for allowing the introduction of thc thread into the said aperture in the dome, each of the said plates being provided directly on its underside with a thread guide, a guiding piece for this latter allowing the thread guide to be shifted during the operation of the machine, and a screw device to secure the thread guide in its adjusted position, the elongated aperture of each said dome being provided with slots having sharp edges allowing the device also to act as an entanglement or union breaker, substantially as described.

In witness whereof I have hereunto signed my naine this th day of August 1906, in the presence of two subscribing Witnesses.
